How do you know which version of the QDM you are using?

Updates to the QDM occur no more than annually and there are currently several versions of QDM available, although each for a different CMS reporting/performance period. See the eCQM Standards and Tools Versions table on the eCQI Resource Center from the eCQI Tools & Key Resources page for the version by reporting year. Each eCQM documentation includes the QDM version number in the CQL file and the HTML human-readable file.
